Emotional manipulation in romantic relationships is a subtle form of controlling a partner through emotional pressure, inducing feelings of guilt, blackmail, ignoring, passive-aggressive behaviors, and other manipulative tactics. However, it is often invisible, elusive, and difficult to prove, which additionally makes this form of abuse highly dangerous. Emotional manipulation can have serious consequences on an individual's mental health, including increased levels of stress, anxiety, and depression. It can also lead to reduced self-confidence, feelings of helplessness, and a loss of control over one's own life. To raise awareness about the harmful effects of emotional manipulation, both for the quality of the romantic relationship, and for the mental health of the individual, this paper presents scientifically-based information on this construct, and describes some of the most common tactics of emotional manipulation, which are used in romantic relationships. Through scientific and professional discussions and education, society can become better informed about emotional manipulation, and create an environment in which victims feel safe to express their issues and seek help.
